I live in Texas and it's my understanding that the IRS gave Texas residents until June 15th to file their taxes or file an extension but I'm trying to file my extension now but Turbo Tax says deadline was 5/15. I don't believe Turbo Tax is accurate that I can't file an extension. Is this true?
The IRS does not allow extensions to be e-filed after May 17. There is nothing that TurboTax, or any other tax software company, can do about it. You have to file your extension by mail.
See the big yellow box at the top of the page at the link below on the IRS web site, which says the following.
Victims in FEMA Disaster Areas: Mail Your Request for an Extension of Time to File
To request an extension to file your federal taxes after May 17, 2021, print and mail Form 4868. . . We can’t process extension requests filed electronically after May 17, 2021.
Extension of Time To File Your Tax Return
if you owe there is another option - one where you do not even mail the form
You can also get an extension by paying all or part of your estimated income tax due and indicate that the payment is for an extension using Direct Pay, the Electronic Federal Tax Payment System (EFTPS), or a credit or debit card. This way you won’t have to file a separate extension form and you will receive a confirmation number for your records.
